exquisite-mart/iPhone / Fraud

i made 2 Orders with this company first i did the first order I purchase 4X Apple iPhone from :exquisite-mart.biz.
I send the money by WESTERN UNION .TOTAL OF $1800.00 we were in contact and they said they will ship with FedEx

but finally they send me tracking number for a courier company called Value Post Express but their phone numbers all diverted non of them are direct numbers.

they don't even have a branch in UAE after few days i checked the tracking online and it says the package has been delivered. i contact the Exquisite Mart and told them about it and they said they made few calls to the shipping company and they response that the package is singned and accepted,

after they told me that they will resend my phone and they ask me to pay for my 2nd order and they will send all together i refused to buy my 2nd order ever since they stop responding to my Emails i contact with different mail account and they reply to all my emails
